fetchmail/sendmail: Domain of sender address does not exist

[Matthias Andree]

(Since freebsd-ports is a public list, too, I am
copying to fetchmail-users mailing list for future reference.
Note that the fetchmail lists only permit subscribers to post.)

Indeed you should.

However, look for "softbounce" in the manual page, it is on by default
in fetchmail versions >= 6.3.10 and < 7.0.0 (not yet released) to avoid
mail loss.

--nosoftbounce on the command line, or "set no softbounce" early in the
.fetchmailrc will cause fetchmail to delete such messages (I should add
a pointer to that section).

I will add a pointer to these options to the quoted section, though, to
appear in v6.3.25.
